Abstract
Abstract Gas metal tungsten (TIG) welding is one of the best suited fabrication methods in industries due to lower capital cost, contamination free and sound quality of weld joints. However, there are few drawbacks like the limited penetration capacity and limited productivity in TIG welding. That is why to improve the productivity attempts are made every now and then through improving the penetration of the TIG welding. In this regard, the Activated Tungsten Inert Gas (ATIG) welding is a unique method, where developed flux combination is pasted onto the surface of the base metal. The flux formulations have been done essentially based on empirical data as well as the practical experience. The in house developed activating flux is applied as a thin coating to the metal surface before welding. It was observed that there was a significant increment in bead penetration and quality through ATIG. Here efforts were made to increase the weld penetration by applying the active flux and to optimize the process parameters. An optimized mixture of MnO2, SiO2 and TiO2 was found to be effective for enhancement of penetration. Content of MnO2 and beam current have significantly contributed for enhancement of penetration and width of bead, respectively.
